Try it on a sample

Paste a numeric sensor series (or pick a sample). Your browser fits a small model library, stores the model + an exact integer residual, and reports the real size vs gzip — byte-exact, never worse than gzip, and queryable from the model. All computed locally.

This is an honest, smaller-scale illustration: it sizes residuals with gzip (CompressionStream) and a handful of models. The production engine uses LZMA, more model families, piecewise regimes, an autoregressive class, SHA-256 integrity, and runs on-prem on your historian. Want it on your data? Request a pilot.
